Pieces of History

Military Logistics of the Canadian Expeditionary Force, 1914–1919

Michel LitalienHistorian

Front-line soldiers cannot fight effectively unless they are fed, clothed and equipped properly and have sufficient ammunition and gear to face the enemy. And they cannot hold their lines for long if they are not supported by solid military logistics.

Canadian military logistics is a dimension of the history of the Canadian Expeditionary Force (CEF) that is often overlooked. Yet just a few days after Canada’s entry into the First World War, it was obvious that there was no way of ignoring it. When huge numbers of military and civilian volunteers showed up at Valcartier, near Quebec City, in August 1914, logistical support services, which had only recently been established, were soon put to the test. Clothing and equipping the members of the first contingent turned out to be a real headache. Manufacturers had to be found and contracts drawn up in a hurry for the production of uniforms, boots, belts, weapons, vehicles and so on. From a logistical standpoint, mobilizing the first contingent destined for Europe was a nightmare.

Throughout the Great War, the Canadian Expeditionary Force’s logistical support system was an immense, complex operation. Of all the support services, the Canadian Army Service Corps (CASC) was the most diversified. Its main responsibilities were transporting combat troops, delivering equipment and materials, and providing the troops with fresh supplies. In addition to these essential tasks, the CASC also evacuated the wounded (ambulance drivers belonged to the corps), salvaged equipment that had been captured from the enemy or left behind on the battlefield and delivered mail. The CASC worked closely with the Canadian Ordnance Corps, the Canadian Army Medical Corps, and the Canadian Artillery Corps for the transportation of specialized ordnance.

The CASC operated from seaports located hundreds of kilometres from the battlefield, all the way to just behind the front lines. Its replenishment system could supply not only small groups of just a few men but also formations the size of an infantry battalion (approximately 1,000 men).

Resupplying front-line units was a multistep process. From ports and depots, supplies were first taken by railway to railheads. From there, CASC units were responsible for moving the supplies by truck or light railway to supply dumps. These operations took place in the third line of supply. Thanks to their small size, light railways could run and reach areas closer to the front lines more easily. It was also harder for enemy artillery to pinpoint them. The administrative area behind the front lines was crisscrossed by light rail lines that were built and maintained by Canadian railway troops.

From the supply dumps, the CASC’s divisional train and ammunition supply column, both of which were horse-drawn, were responsible for bringing supplies closer to the front lines, to their respective divisions or individual units. This was the second line of supply.

Lastly, operations to supply front-line units constituted the first line of supply. These units had to come back to the rear to get their own supplies of gear, ammunition, weapons, technical and communications equipment, water, medication and food. These supply expeditions were carried out chiefly at night so that the soldiers could not be seen by the enemy. But assigning combat troops to this task meant that a battalion’s defensive positions at the front would be short of manpower for a time and so vulnerable to enemy attack.

Toward the end of the war, however, a Canadian officer from Montreal proposed using the tumpline system — the method that Canada’s aboriginal people and coureurs de bois had used to carry large loads on foot. Before the introduction of this system, infantryman had to carry supplies in their arms, thus limiting the quantity of materials due to their size and weight. The tumpline system, which involved the use of a head strap, allowed the soldiers to carry more weight and freed up their arms, thus giving them more freedom of movement. With this system, each soldier was able to transport a greater quantity of supplies and so fewer men were required for the job, leaving more troops to ensure the defence of the front lines.

Besides regularly providing drivers and vehicles to other units, the CASC also maintained and repaired its vehicles. It also had to make sure that the troops were fed, which meant that fresh and hard rations had to be allocated and distributed properly; its military cooks oversaw the operation of field bakeries and butcheries.

The CASC was not the only logistical support corps to play a key role in the CEF. The Canadian Ordnance Corps was responsible for procuring, storing and distributing uniforms, boots, equipment, weapons, ammunition and shells to combat troops. Specialized supply depots, located in the second line of supply, helped ensure more effective distribution.

The Canadian Ordnance Corps’ other major role was to maintain equipment in the field. The repairmen in the specialized ordnance mobile workshops could get closer to the deployed units and repair their weapons, both light and heavy, as well as their equipment. If the mobile workshops were not able to do the repairs on site, the weapons and equipment were shipped to heavy or stationary workshops at the rear, where virtually anything could be reassembled or rebuilt. The small detachments of the Ordnance Corps worked closely with the various units of the Army Service Corps.

Despite the gradual mechanization of the war, horses remained a vital component of the CEF. The cavalry, the artillery and, of course, the Army Service Corps used huge numbers of horses right up to the end of the war. At one point, Canadians were using as many as 24,000 horses and mules in their overseas operations. Horses could often manage in places where motorized vehicles could make no headway! Inevitably, some horses suffered injuries or fell ill. The Canadian Veterinary Corps operated mobile sections to take care of horses; it also ran veterinary hospitals for horses, advanced remount depots and specialized basic provisions depots.

Other logistical support services also played a crucial role in enabling combat troops to get on with their job. The Canadian Postal Corps, for instance, helped maintain the morale of soldiers at the front, at the rear and also those convalescing in hospitals. Army chaplains, who constituted the smallest organized support group, provided religious services to Canadian soldiers of different faiths and offered moral support at difficult times. Lastly, despite the enemy’s efforts to maintain a naval blockade by submarines, the Canadian Forestry Corps ensured that Great Britain, France and the Canadian Expeditionary Force obtained all the timber they needed to carry out their military operations.

Thousands of men served in these various organizations. The Army Service Corps, for example, counted over 17,000 officers and non-commissioned soldiers in its organization. Even if these units were not combat troops, many of them, including the Army Service Corps, played important roles in all military actions. One hundred and four members of the CASC were killed, and 363 were wounded.

Artillery: The Great Killer

Tim CookHistorian, Canadian War Museum

The Great War has often been called the gunner’s war. “The artillery conquers and the infantry occupies,” remarked one French general. That was too simplistic, of course, as infantry tactics developed throughout the war, but the artillery barrage was the key to victory or defeat.

In 1914 and 1915, artillery proved it was the great killer. For those caught in the open, shrapnel and high explosive shells wreacked havoc. Thousands were left rotting on the battlefields. However, artillery guns were vulnerable to small arms fire, and they could be driven away from the front. But the guns were soon firing indirectly from hidden positions several kilometeres to the rear, still causing terrible damage. Soldiers were forced to find safety in trenches, digging beneath the ground to escape the murderous fire.

As trenches were strengthened with barbed wire, deep dugouts, and machine -guns, an enormous weight of fire was needed to smash the enemy defences and support the infantry. But there were not always enough shells in the early years to feed the guns. And so the infantry were killed in the tens of thousands as they attacked undamaged enemy trenches in frontal assaults. As the war lengthened, artillerymen received nearly unlimited supplies of shells through the enormous production of munitions factories. New tactics were also developed to improve the accuracy of the guns.

Artillery shells contained high explosives, shrapnel, and, later in the war, poison gas and smoke. Both the high explosive and shrapnel shells were timed to detonate in the air above a target. High explosive shells blasted holes in the trenches and the concussion alone could kill, as lungs collapsed under the force of the explosion. Shrapnel shells were equally deadly, consisting of more than 300 rounded metal balls that exploded downward in a cone-shaped rain of whirling metal. As well, the casing of the shell was designed to explode outward, creating jagged, uneven shards of steel that tore through flesh.

By 1916, commanders believed that massive artillery shoots, involving hundreds of thousands of shells, would annihilate the enemy defenders. This would allow the infantry to punch a hole through enemy lines and restore mobility on the Western Front.

However, it was often hard to hit, and then destroy, the narrow and well-fortified trenches. The problem also lay in the shell fuses. Earlier types were not sensitive enough to explode on contact, especially with shells tasked to clear barbed wire. As a result, many of the shells exploded in the ground, killing very few of the enemy, leaving the infantry to fight their way through defences-in-depth. By the end of 1916, newer, sensitive fuses that exploded on the slightest contact harnessed the destructive power of the artillery and, equally important to the infantry, cleared barbed wire from in front of enemy trenches.

Tactics again changed during the later phases of the bloody battles of the Somme in the last half of 1916. The gunners would never be able to destroy all of the German defences, and even one machine -gunner could kill hundreds of attacking infantry. Instead, the artillery sought to suppress enemy fire through a “creeping barrage,” and give their own attacking infantry enough time to cross the killing zone of nNo Mman’s Lland.

Gunners fired their shells to create a “creeping” wall of fire that slowly moved forward over the enemy lines at fixed intervals: 50 yards (46 m) every couple of minutes, less for muddy ground, more for open warfare. In effect, it was a screen of fire and explosives. As this moving wall of shrapnel and high explosives chewed up the ground in its path, the infantry were told to “lean into the barrage” and stay as close as possible. Although friendly fire was expected and occurred, the casualties would still be lighter than if the creeping barrage moved off and allowed German machine -gunners, waiting in the safety of deep dugouts, to get to the top of their trenches before the infantry crossed nNo Mman’s lLand.

At the Battle of Vimy Ridge in April 1917, the gunners had perfected the creeping barrage. Yet enemy gunners still took a fearful toll as they laid down their own counter-barrages to catch the follow-on waves of infantry. The enemy guns had to be stopped, or slowed, but it was exceedingly difficult to identify, target, and destroy camouflaged guns several kilometeres away.

Accurate intelligence was essential, and new and refined forms of science aided the gunners. The Canadian Corps was lucky to have Brigadier-General Andrew McNaughton, commander of the counter-battery office for much of the war, who embraced new technology and tactics. A prewar professor at McGill University, he turned to science to save his soldiers lives.

The Canadian Counter Battery Office (CCBO), established in February 1917, gathered intelligence and processed information on the enemy to assist in knocking out his guns. Aerial reconnaissance from the Royal Flying Corps (later Royal Air Force) was of great assistance as airmen photographed the front from great heights. Later in the war, observation aircraft circled the battlefield, passing real-time information to the gunners through letter drops and primitive wireless radio.

As the CCBO developed after April 1917, this information-gathering and target-selection became more sophisticated, with new technology, like sound-ranging and flash-spotting, assisting gunners to find and destroy enemy targets.

Flash-spotting involved the coordination of observers. At least three posts were needed, usually spread out along several kilometeres. When an enemy gun position was spotted by the revealing flash as the shell left the barrel, the observers were telephoned by headquarters to turn their attention to that spot. After studying the flash of the gun, the observers would hit a key that was connected to a lamp at headquarters. From the observers’ bearings, and by triangulating their estimates, enemy guns could be located with high precision.

Sound-ranging worked on a similar principle. Listeners sat two kilometeres behind the line with their microphones. Additional posts were manned well ahead of these positions. As long as there was not more than one shell per second being fired, on hearing the crash of an enemy gun, the forward listening post pressed a key that started an oscillograph, an instrument that recorded on film the sound of the shell in flight as it reached each microphone in turn. The time-intervals between the microphones allowed the CCBO to analyse the information and, if conditions were optimal, pinpoint enemy guns to within twenty-five 25 yards (23 m). All available counter-battery guns would be aimed on that spot to deliver a destructive shoot of 50-100 shells. Chemical shells were also used to kill or force the enemy gunners to wear debilitating respirators that severely affected the rate of fire.

In the last year of the war, artillery had perfected the creeping barrage and was steadily improving its counter-battery work. Further tactical refinement allowed gunners to fire more complicated barrages, like a box barrage. The box barrages set up a wall of fire and explosives around an enemy position —-- usually a trench —-- which effectively isolated it from reinforcements. It allowed assaulting Canadian infantrymen to capture and consolidate a position without fear of immediate counterattack.

By war’s end, 43,914 gunners had served in the Canadian artillery, and 2,565 had lost their lives from disease, injury, and battlefield wounds. They had fired tens of millions of shells, reducing the landscape to a desolate wasteland, and an estimated 60% of all wounds were inflicted by shell fire. The First World War was indeed a gunner’s war.

Demobilization

Discussion of the procedure to be followed in demobilization had begun at the end of 1916, and from then to the end of the war there had been two years of careful planning by the Department of Militia and Defence and the Overseas Military Forces of Canada to ensure that when the time came, the return to Canada should be carried out speedily, that the transportation provided should be as comfortable as possible, and that the troops should receive a "fair deal" in the priority in which they sailed. The Canadian decision to demobilize its overseas troops was taken immediately after the signing of the Armistice, and a week later the Cabinet authorized demobilization of C.E.F. units then in Canada.

The original estimate that at least eighteen months would be required to bring back all overseas troops proved excessive. Two-thirds of the overseas force reached home within five months, and before a year had passed repatriation was virtually completed. On November 13 1918 the British Ministry of Shipping advised the Canadian Government that ships would be available to move 50,000 troops each month; and in spite of strikes which cancelled individual sailings, shipping was never a real problem. But during the winter of 1918-1919 Canadian railways could handle less than 25,000 troops in a month; and even when disembarkation could take place at the St. Lawrence ports, with a resulting shorter rail haul, the capacity of the vessels available considerably exceeded that of the troop trains. Wisely the Militia Department called for expert assistance from the Minister of Railways and the presidents of the three major railway systems. High officials of the companies formed a railway demobilization committee which was able to increase the monthly carrying capacity to a total of 45,000 troops.

Each soldier had the right to choose his destination in Canada. In order that each might be demobilized at a point near this destination, twenty-two Dispersal Areas were set up in Canada by subdividing the existing eleven Military Districts. At the concentration camps established in the United Kingdom troops from the continent, as well as those already in England, were regrouped and distributed among twenty-two wings, each matched to a Dispersal Area in Canada. From these camps units of the Canadian Corps entrained direct for the port of embarkation, but for troops outside the Corps a large staging camp was organized at Kinmel Park, thirty miles from Liverpool. Only the 3rd Division (which headed the Corps move) and Corps Troops were not regrouped, but returned to Canada in the units in which they had fought.

At the concentration camps the soldier completed his documentation and received his final medical and dental clearances. His kit deficiencies were replaced, his pay account adjusted, and he filed his application for his War Service Gratuity. He was then granted demobilization leave of from eight days to two weeks. On his return he received his Last Pay Certificate and was posted to an embarkation company to await sailing. In all, the average soldier spent about a month in England. There were some cases when for compassionate reasons individuals returned home in advance of normal sailings. Unfortunately, though these were few, they were a cause of dissatisfaction to soldiers who did not understand the circumstances involved. Furthermore, for considerations of economy and to keep ships filled, certain untrained drafts were sent back to Canada soon after their arrival in the United Kingdom.

These modifications to the policy of "first over, first back", aggravated by disappointment brought about by the cancellation of individual sailings, were at the root of some of the rioting which occurred at several Canadian camps. Men were being brought home as fast as the available ships and trains could move them, but not as rapidly nor in the order in which some desired to come. There was resentment over the fact that the 3rd Division - which included many Military Service Act men with comparatively little service - was given precedence over the other divisions. Unfortunately not enough effort appears to have been given to explain the reasons for the delays, unavoidable as they were. In all, between November 1918 and June 1919, there were thirteen instances of riots or disturbances involving Canadian troops in England.

The most serious of these occurred at Kinmel Park on March 4 and 5 1919, when dissatisfaction over delays in sailing precipitated rioting by upwards of 800 soldiers which resulted in five men being killed and 23 wounded. Seventy-eight men were arrested, of whom 25 were convicted of mutiny and given sentences varying from 90 days' detention to ten years' penal servitude. At Witley, on the night of 14-15 June, a small group of dissidents started trouble by trying to free some soldiers arrested for persisting in playing Crown and Anchor in defiance of previous regulations curbing widespread gambling in the camp. The disturbance spread to canteens and the civilian area. On the following night the Garrison Theatre was burned and nearly all the civilian shops in the area were destroyed. Similarly at Epsom on June 17, the indiscipline of a small minority was to blame when a civilian police station was stormed, one policeman was killed and seven others injured.

On June 20 1919, Lieut.-General Sir R. E. W. Turner, V.C., Chief of the General Staff, O.M.F.C., published a Special Order of the Day warning all troops of their individual responsibility to quell such disturbances. He made clear in no uncertain terms that the incidents that had occurred were acts of mutiny, and that to remain a passive spectator in such a situation was to side with the mutineers. The order appeared to have a good effect upon the troops; at any rate, there were no further disturbances. The outbreaks had been regrettable, particularly as there seems little doubt that the unrest which produced them might have been considerably lessened had more publicity been given to explaining the reasons for having to modify the plans for demobilization.

Despite attempts by the Canadian Government to discourage the discharge of soldiers in the United Kingdom, 15,182 men signed away their right to free transportation home and remained in England. This total, added to 7136 who had already been discharged there before the Armistice, meant that in all some 22,000 Canadian soldiers entered civil life in the United Kingdom.

In Canada demobilization proceeded smoothly and expeditiously. On the arrival of a troopship at a port of disembarkation, the Clearing Services welcomed the soldiers and their dependents - an estimated 54,000 relatives accompanied the returning troops – and arranged for their transportation inland to the Dispersal Areas. Immigration officers worked closely with the military authorities, so that an average train, carrying about five hundred troops, could be loaded in thirty minutes. Spirits were high as the trains rolled rapidly westward; those with only one night on board found in the excitement of nearing home little time for sleep. The heart warming reception given by cheering crowds as the train drew into its destination was repeated in cities all across Canada. In many cases the returning unit would form up outside the railway station for its last march - a proud parade through thronged streets to the place of dismissal. Then came the last order by the Commanding Officer. The men turned right and broke off - and another unit of the
Canadian Expeditionary Force passed into history.

The final stages of demobilization were quickly effected. The soldier turned in his arms and equipment (retaining his clothing and steel helmet), had his medical history sheet signed, and received his war badge, his cheque and his discharge certificate. The careful documentation carried out in England and on the ships now paid off, as men passed through the dispersal station at the rate of about six every minute. Every soldier who had been overseas for six months and every one who had served in Canada for a full year received a gratuity based on his length of service and the rate of pay of his rank. (For overseas service, single privates received payments which varied from $420 - for three years' service or more - to $210 for service of less than a year.)

Those veterans who wanted to establish themselves on the land were assisted with long-term loans; in this way the Soldier Settlement Board withdrew more than 30,000 soldiers from the general labour market and directed them into agriculture. For the disabled, there were pensions and medical treatment and opportunities for vocational training. Up to the end of 1919, a total of 91,521 pensions had been granted, amounting to some $22,500,000 annually. At the same time 8000 soldiers were receiving medical treatment, while more than 23,000 were enrolled for vocational training.50 In such manner did a grateful country attempt in some measure to repay its debt to those who had served and survived.

After Amiens

Although by August 13 1918 the Allied offensive had been definitely checked, the German leaders could no longer doubt that the initiative had passed from their hands. On that date, at a conference held at Spa with Field-Marshal von Hindenburg, Reichschancellor Count von Hertling and the Foreign Secretary, Admiral von Hintze, in attendance, Ludendorff, while opposing any voluntary surrender of ground, admitted "that it was no longer possible to force the enemy to sue for peace by an offensive". Since the defensive alone could hardly achieve that object, the war would have to be ended by diplomatic means. Hindenburg, on the other hand, derived some comfort from the fact that "the enemy had once more failed to extract all possible advantages from his great initial successes" and that German armies were "still standing deep in the enemy's country." Next day, at a Crown Council presided over by the Kaiser, His Majesty ordered peace negotiations to be opened through the King of Spain or the Queen of the Netherlands.187 It was also about this time that orders were issued calling off large-scale air attacks planned against the British and French capitals by German bombers using thousands of one-kilogram incendiary bombs. While it was proclaimed to the world that these cities were being spared on humanitarian grounds, there seems little doubt that the inevitability of a German defeat was the main reason for the cancellation of the attacks. Throughout the war British and French planes dropped some 14,000 bombs on German soil. A British plan to attack Berlin, however, failed to materialize owing to insufficient aircraft capable of such a mission.

In the meantime Allied plans on the Western Front were undergoing revision. As early as the evening of August 11, as German resistance stiffened, Marshal Foch had shown himself willing to modify objectives and consider alternatives to further offensive operations on the Amiens front. At that time large-scale operations were due to be resumed on the 15th. But on the 13th General Debeney asked for and received a day's postponement of the assault by his army; and next morning General Rawlinson was given the same extra time in which to complete his preparations. Sir Douglas Haig has revealed in his diary that he shared Rawlinson's misgivings about attacking the well-prepared Roye-Chaulnes defences and that he was resolved that the French First and British Fourth Armies should merely "keep up pressure on that front" in order to hold the enemy's attention, while he prepared to strike elsewhere with the British First and Third
Armies.

There is no doubt that Rawlinson was considerably influenced by representations made to him by General Currie, upon whose forces the burden of a major share of a renewed offensive must fall. At a meeting on the morning of August 14 the Army Commander showed Haig a letter (accompanied by air photographs taken the previous day of the German positions) in which Currie set forth the arguments against renewing an operation which would "cost a great many casualties" without obtaining adequate results. He suggested that if the attack were found to be absolutely necessary it should be postponed in order to allow time to "recover the element of surprise." He recommended that an alternative, and better, course would be to withdraw the Canadian Corps from the line, and after resting it for a few days employ it on the Arras front in a surprise attack in the direction of Bapaume. An advance in this sector coupled with an attack by the French from their present line, might well force the enemy to abandon his positions west of the Somme without the necessity of a frontal assault.

This last suggestion was in keeping with Haig's own ideas. An exchange of letters with Foch on the 14th brought no agreement about postponing operations at the Somme, and that evening a telegram from the Generalissimo asked Haig "once more to maintain the date already set." The Field Marshal, however, had made up his mind to limit the Somme attack to a series of set stages, and on the afternoon of the 15th he pressed his arguments at Foch's advanced headquarters at Sarcus (twenty miles south-west of Amiens). "I spoke to Foch quite straightly", his diary records, "and let him know that I was responsible to my Government and fellow citizens for the handling of the British forces." Foch's resistance had already been weakened when he learned from General Debeney that morning that the projected attack on Roye "would certainly be difficult", and even if mounted would leave the French forces too weak to maintain it. "I definitely came around to the opinion of Field-Marshal Sir Douglas Haig", he wrote in his Memoirs, and he agreed that the Amiens offensive should not be pressed.

A new operation order issued by British G.H.Q. directed the Third Army, which was holding a nineteen-mile front north of Albert, without delay to "press the enemy back energetically in the direction of Bapaume"; the Fourth Army while continuing its preparations for an attack would be prepared to follow up any German withdrawal towards the Somme. Farther north the First Army would take advantage of any German retirement to exert pressure south-eastward from the Arras sector; under favourable conditions, it would attack Monchy-le-Preux and Orange Hill.

In a letter confirming his acceptance of Haig's proposals Marshal Foch made it clear that he was depending on the British operations to be developed with sufficient impetus to ensure a resumption of the thrust south of the Somme. He went on to thank Sir Douglas for his cooperation, which had completely freed the Amiens area and the Paris-Amiens railway. For an offensive north of the Aisne he was now going to transfer the French First Army from Haig's command back to Pétain's group of armies. Accordingly the Franco-British boundary was shifted northward to the Amiens-Chaulnes railway, and the relief of the Canadian Corps by French troops began on 19 August.

On the night of August 19-20 the 2nd Canadian Division began moving northward by bus and train to rejoin the First Army in the Arras sector, followed the next night by the 3rd Division. A number of days were to elapse before the 1st and 4th Divisions made the move. General Currie closed his Headquarters at Dury on the 22nd. During the day he called on a number of senior commanders and had the satisfaction of being told by General Byng that the Canadian performance at Amiens was "the finest operation of the war".
